GOLD-CATCI -IING DENTAL-CUSPIDOR ATTACHMENT.

To all whom. it may concern:

Be it known that I, Dr. ROBERT M. Free, a citizen of the United States,and a resident of Le Mars, in the county of Plymouth and State of Iowa,have invented certain new and useful Improvements in Gold CatchingDental-Cuspidor Attachments, of which the following is a specification,reference being had to the accompanying drawings, forming a part of thisspecification.

This invention relates to certain new and useful improvements indentists spittoon attachments. The special object of the invention is toprovide a device for saving the gold particles.

Another object is to provide a simply constructed positively operatingcuspidor attachment whereby the small gold particles removed in grindingand polishing gold filled teeth may be saved.

With these and other objects in view the present invention consists inthe combination and arrangement of parts as will be hereinafter morefully described and finally pointed out in the appended claims, it beingfurther understood that changes in the specific structure shown anddescribed may be made within the scope of the claims without departingfrom the spirit of the invention.

In the accompanying drawings forming a part of this specification and inwhich like numerals of reference indicate similar parts in the severalviews Figure 1 shows an elevational view with parts broken away of agold catching device embodying my invention disclosing the same asattached to a dental fountain spittoon.

Fig. 2 is a section on line 2, 2 of Fig. 1.

Fig. 3 is a top view of one of the tray forming members.

In my present invention, I provide a simply constructed attachmentarranged to be used in connection with a dental cuspidor whereby thegold particles removed in grinding gold filled teeth which haveheretofore been. an entire loss, are saved.

In the accompanying drawing I show a gold catching device embodying myinvention as attached to a fountain spittoon A, which is inconnectionwith the usual water pipe 1.

My invention proper comprises a housing made of two tubular membersbothofequal length which are secured by means of a pipe connection D,near one end, as shown in Specification of Letters Patent. Pgfl gntedItiay 14,, 1531 Application filed July 17, 1917. Serial N0. 181,185. 7

By means of a nipple Z; the upper tubular member B is secured to theneck a of the spittoon A.

The member B has both of its ends closed by means of suitable caps 2 and3 while the lower member C has one end closed by means of the cap 4:,the other end being secured to a pipe connection 5, in the form of abend, to which is secured an ordinary S- trap 6 from which extends theover flow pipe.

Held within the upper tubular member B is a flat top base member 11which snugly fits into the lower portion of the housing B as shown inFig. 2 and removably held upon the top 11 is the gold catchingtray-forming member 12 which member is provided with a plurality oftransversely extending spaced grooves 14 between which are locatedgroops of semi-circular depressions 15 which serve as wells in catchingthe gold particles as they are carried through the housing by means ofthe water escape in flushing the cuspidor. a

The t o members B and C with the con. nection D form a water way throughwhich the old carr in water asses in findin an escape to soil pipe.

The lower member C is provided with a simple fiat member 10 closelyfitting into what forms the bottom portion of the tubular member andremovably held on this member 10 is the gold tray-forming member 13 alsoprovided with a plurality of transverse grooves l l and groups ofsemi-circular depressions 15.

The members B and O are secured in superposed horizontal spaced relationand held by means of a suitable bracket 9 which bracket is provided withthe outwardly curved clasping portion 17 and upper clasping portion 16used in conjunction with a yoke comprising an upper olasping portion 4withdraw the trays and remove the col-' lected precious metal.

Having thus described my said invention, what I claim as new and desireto secure by U. S. Letters Patent is 1. A gold catching device of thecharacter described including a housing comprising tWo superposedtubular members held in spaced relation, said members being connectednear one end, and said upper tubular member being arranged to be broughtinto connection With a dental spittoon, caps for closing the ends ofsaid upper member, said lower member at one end being connected to anS-trap, a cap for closing the other end of said lower member, a flat topbase member closely fitting into the bottom portion of each of saidtubular members and a removable tray-forming member held upon each ofsaid base members, each tray member having a plurality of transversegrooves arranged in spaced relation, with a plurality of semi-circulardepressions between said grooves.

2. A dental spittoon attachment compris- 7 ing two connected tubularmembers one of said members being adapted to be connected to a dentalcuspidor, the other member ar ranged to be connected to an S-trap, and agold catching tray removably held Within each of said tubular members,all arranged as and for the purpose set forth.

In testimony whereof I atlix my signature in the presence of twoWitnesses.
